Product construction is the first major distinction. Review our woven vs nonwoven geotextile comparison before comparing individual specifications.
Continuous Filament Nonwoven Geotextile
Continuous-filament nonwoven geotextile is manufactured from continuous synthetic filaments formed into a needle-punched fabric.
Depending on the product specification, it may be considered for:
- filtration and separation;
- drainage support;
- geomembrane cushioning and protection;
- road and earthwork construction;
- landfill, pond and reservoir liner systems.
Important properties may include mass per unit area, thickness, tensile strength, elongation, CBR puncture resistance, apparent opening size and permittivity.

Staple Fiber Nonwoven Geotextile
Staple-fiber nonwoven geotextile is produced from shorter synthetic fibres mechanically bonded into a permeable fabric.
Depending on its structure and tested properties, it may be used for:
- filtration;
- separation;
- subsurface drainage;
- road construction;
- landscaping;
- protection applications.
Two staple-fiber products with the same GSM may still have different thickness, strength, opening size and water-flow properties. Buyers should compare the full technical data rather than fabric weight alone.
Recommended button:
Woven Geotextile Fabric
Woven geotextile is manufactured by interlacing synthetic yarns, tapes or filaments into a structured fabric.
It is commonly considered for:
- separation between subgrade soil and aggregate;
- granular-layer stabilization;
- road and working-platform construction;
- selected filtration applications;
- earthworks requiring defined tensile properties.
Not all woven geotextiles are the same. Slit-film woven, monofilament woven and multifilament woven products can have different opening structures, hydraulic properties and intended functions.
The product page should therefore clearly identify the actual woven construction and current technical data.

What Does Geotextile Do?
Geotextile can perform several different functions, depending on its construction and position in the system.
Filtration
The fabric allows water to pass while helping limit unacceptable migration of surrounding soil particles.
Separation
It helps prevent the mixing of natural soil and granular material, such as subgrade and aggregate.
Protection
Nonwoven geotextile may provide cushioning between a geomembrane and rough soil, aggregate or other potentially damaging surfaces.
Stabilization
Selected woven or nonwoven products may contribute to improved performance in granular layers when the complete road or platform system is properly designed and installed.
Drainage support
Geotextile can act as a filter around drainage aggregate, perforated pipes or drainage cores.
However, a standalone geotextile should not automatically be treated as a replacement for a drainage core, collector pipe or functioning outlet where significant water transport is required.
What Geotextile Does Not Replace?
Geotextile should not be treated as a universal solution for every soil or drainage problem.
It does not automatically replace:
- a geomembrane waterproof barrier;
- a functioning drainage outlet;
- a drainage core where in-plane water transport is required;
- project-specific reinforcement design;
- proper subgrade preparation;
- suitable aggregate;
- installation quality;
- geotechnical evaluation.
Not every geotextile is intended for reinforcement, and not every woven product is suitable for filtration.
The required function should be defined before comparing product types.
PP and PET Geotextile Materials
Polypropylene and polyester are common polymers used in geotextile products.
Polypropylene and polyester may be used in different woven and nonwoven constructions. Review our available PP/PET needle-punched geotextile specifications for current material and product options.
Polypropylene Geotextile
PP may be used in both woven and nonwoven products. The actual performance depends on the manufacturing structure, polymer formulation and tested product properties.
Polyester Geotextile
PET is commonly used in selected continuous-filament, staple-fiber and woven products. Suitability should be evaluated using the current technical data and relevant exposure conditions.
The polymer name alone does not determine:
- filtration performance;
- strength;
- hydraulic properties;
- installation resistance;
- service life;
- project suitability.
For this reason, PP/PET geotextile should be treated as a materials section rather than a single product category unless the page represents one clearly defined product.
Geotextile Applications
Road Construction
Geotextile may be installed between subgrade and granular layers to provide separation, filtration or selected stabilization functions.
Road-product selection should consider:
- subgrade condition;
- soil variability;
- aggregate gradation;
- drainage;
- construction traffic;
- installation survivability;
- project specification.

Drainage and Filtration
Geotextile filter fabric may be used around drainage aggregate, trenches and perforated pipes to allow water passage while limiting soil migration.
Selection should consider soil gradation, AOS, permittivity, installation strength and clogging risk.

Geomembrane Protection
Nonwoven geotextile may be installed below or above geomembrane to reduce direct contact with uneven or potentially damaging materials.
Protection requirements depend on:
- subgrade condition;
- stone size and angularity;
- overlying materials;
- applied pressure;
- puncture risk;
- installation procedure.
The geotextile provides protection but does not create the waterproof barrier.

Retaining-Wall Drainage
Geotextile can separate retained soil from drainage aggregate or form the filter layer of a composite drainage system.
The complete drainage system may also require:
- selected drainage aggregate;
- perforated collector pipe;
- drainage board;
- waterproofing;
- a functioning discharge point.

Erosion Control and Riprap
Geotextile may be used beneath riprap and selected erosion-control systems as a filter and separation layer.
Relevant factors can include:
- surrounding soil;
- water flow;
- AOS;
- permittivity;
- puncture;
- abrasion;
- rock-placement damage.

Key Geotextile Specifications
| Property | Why it matters |
|---|---|
| Product construction | Distinguishes nonwoven, slit-film woven, monofilament and other products |
| Polymer | Identifies whether the product is PP, PET or another material |
| Mass per unit area | Supports product identification and production consistency |
| Thickness | May be relevant to cushioning and product structure |
| Tensile strength | Describes response under a defined tensile test |
| Elongation | Helps explain deformation behaviour during tensile testing |
| Tear resistance | Relevant to handling and installation |
| CBR puncture resistance | Important around coarse or angular materials |
| AOS | Supports preliminary soil-retention assessment |
| Permittivity | Indicates cross-plane water passage under defined conditions |
| Water-flow rate | Useful when methods, units and test conditions are consistent |
| UV resistance | Relevant where temporary exposure may occur |

Not every property has the same importance in every application.
For example:
- filtration projects focus more on AOS, permittivity and soil compatibility;
- road-separation projects also require installation survivability;
- geomembrane-protection applications may place greater emphasis on thickness, cushioning and puncture resistance.

How to Choose Geotextile Fabric
1. Define the required function
Determine whether the main requirement is filtration, separation, protection, drainage support or stabilization.
2. Identify the surrounding materials
Consider the soil, aggregate, geomembrane, drainage core or other materials in contact with the fabric.
3. Review hydraulic requirements
For filtration applications, check AOS, permittivity, water-flow requirements and soil compatibility.
4. Review mechanical requirements
Check tensile, elongation, tear and puncture properties against the expected handling and installation conditions.
5. Confirm product construction
Do not compare needle-punched nonwoven, slit-film woven and woven monofilament products as though they were interchangeable.
6. Compare the reporting basis
Confirm whether the values are:
- typical;
- minimum;
- MARV;
- maximum;
- guaranteed.
7. Follow the project specification
Final product selection should follow the contract documents and responsible engineer’s requirements where project design is involved.
Technical Data and Quality Documentation
Depending on the product and project requirement, available documentation may include:
- current product data sheet;
- product identification and polymer information;
- sample certificate of analysis;
- batch or production records;
- third-party test reports;
- roll labels;
- packing information;
- production and testing photographs.
Test values should be compared only when the following are consistent:
- test method;
- units;
- product direction;
- specimen condition;
- reporting basis.
A marketing name such as “heavy duty,” “premium” or “Type 4” should not replace the required technical properties.
Packaging and Export Supply
Available packaging should be confirmed for the selected product and roll size.
Commercial information may include:
- roll width and length;
- roll diameter;
- roll weight;
- core type;
- external wrapping;
- product label;
- container-loading quantity;
- shipping port;
- production lead time.
Roll dimensions can affect installation efficiency, overlaps, handling and shipping cost. They should be considered together with the product price per square metre.
Information Needed for a Geotextile Quotation
For a more useful quotation, provide the following information:
| Required information | Example |
|---|---|
| Application | Road, drainage, liner protection or erosion control |
| Required function | Filtration, separation, protection or stabilization |
| Product type | Woven or nonwoven |
| Polymer | PP, PET or project-specified |
| Mass | GSM or oz/yd² |
| Hydraulic properties | AOS, permittivity or flow rate |
| Mechanical properties | Tensile, tear or puncture |
| Required standard | ASTM, ISO, AASHTO or project specification |
| Roll size | Width and length |
| Quantity | Total square metres or rolls |
| Documentation | TDS, COA or third-party test report |
| Destination | Port or delivery address |
A request based only on GSM may be sufficient for an initial price, but it may not establish technical equivalence.

Frequently Asked Questions
What is the difference between woven and nonwoven geotextile?
Woven geotextile is manufactured by interlacing yarns, tapes or filaments into a structured fabric. Nonwoven geotextile is formed from fibres or filaments bonded mechanically or thermally.
Woven products are commonly used for separation and stabilization, while nonwoven products are frequently used for filtration, drainage support, separation and protection. Actual suitability depends on the product structure and tested properties.
Which geotextile is commonly used for drainage?
Needle-punched nonwoven geotextile is commonly evaluated for conventional drainage and filtration systems. However, woven monofilament products may also be specified for selected engineered filters.
The surrounding soil, AOS, permittivity, clogging risk and installation conditions should be reviewed.
Can geotextile be selected by GSM alone?
No. GSM describes mass per unit area but does not independently determine tensile strength, puncture resistance, AOS, permittivity or soil compatibility.
Products with the same GSM may have different structures and performance.
Is geotextile the same as geomembrane?
No. Geotextile is generally permeable and is used for filtration, separation, drainage support or protection.
Geomembrane is a low-permeability barrier used for containment and waterproofing. The two materials may be used together in a liner system.
Can geotextile replace geogrid?
Not automatically. Geotextile and geogrid may perform different functions.
Geotextile commonly provides filtration, separation and protection. Geogrid is frequently used for reinforcement or granular-layer stabilization. Some projects may use both products.
What information is needed before ordering geotextile?
Provide the application, product type, required function, polymer, GSM or oz, relevant mechanical and hydraulic values, roll dimensions, quantity, required documentation and destination.
Where available, send the complete specification or BOQ.
